casing, D. This inner casing contains within To all whom it may concern:

Be it known that l, J OSEPH JOHN TYLOR, a citizen of Great Britain, residing at 2 Newgate Street, London, in the county of Middlesex,

5 England, have invented certain new and useful Improvements in Liquid-Meters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 0 it appertaius to make and use the same.

This invention relates to rotary water-Ineters; and it consists'in the combination of an outer casing with a removable inner casing, a fan, brake, spindle for the fan, and a pivot for rs supporting it, the four latter parts being containedwithin said inner casing and removable therewith.

The said invention further consists in the combination of an outer casing having an in ternal annular shoulder and a packing thereon with a removable inner casing, and a fan, brake, fan-spindle, and pivot, all contained within said inner casing and removable therewith.

The said invention further consists in the combination of a removable inner casing having an external annular beveled shoulder with an outer casing having an internal elastic packing-ring, which fits on said shoulder and is compressed thereby to form a water-tight joint.

The said invention further consists in the stationary adjustable brake J, hereinafter described, arranged between the inlet and the 3 5 outlet, with the fan and casings of a liquid-meter, substantially as hereinafter set forth.

In the accompanying drawings, Figure l represents a vertical central section through my improved meter; Fig. 2, a horizontal sec- 0 tion on the line at x of Fig. 1; Fig. 3, a plan view of said meter. Figs. 4, 5, 6, 7, and 8 represent detail views.

A designates the outer casing of the meter, having in one side of it the inlet-opening A, It is also provided with an interior shoulder and a recess below the same, which receives a rubber packing-ring, B.

In measuring hot water I use an inclined 5o shoulder without the said packing-ring B, said shoulder being grooved to fit a beveled annular shoulder, D on the exterior of the inner it the fan F, the fan-spindle E, the stationary adjustable brake J, and the pivot E,which supports the lower end of said spindle, all of these parts being removable with said inner casing. The upper end of said spindle is journaled in said casing at the upper end of the latter, and the part of said casing around the upper end of said spindle, which projects slightly above said casing, constitutes an oilcup. Said spindle carries above said casing aworm, G, which gears with a worm-wheel, H, on a shaft, I, whereby the registering mechanism is driven.

The entire inner casing and mechanism contained therein may be easily removed and easily replaced, and the inclined or beveled face of the annular shoulder D and the elastic packing B will compensate for any slight difference in size or shape, so as to make these inner casings interchangeable, instead of the same outer casing requiring always the same inner casing or one of the same exact size and shape to make a good fit.

The inner casing, D, is provided with two or more oblique inlets, D, below said brake J, and with three outlets, D arranged above said brake at equidistant points around the perimeter of said inner casing. There are two an nular spaces between the outer and inner casing-one connecting the said inlets D one to another and to main inlet A, and the other the out-lets D one to another and to main outlet A. In the former annular space an annular filter or strainer, O, is preferably inserted between the main inlet A and the inlets D of the inner casing.

The water or other liquid fluid or gas flows in through openings A and D. turns the fan F, ascends through openings J of brake J, and passes out through openings D and A. The function of the brake J is the usual one of resisting the action of the inflowing liquhl,

so that volume will be registered and not velocity. It becomes very important to regulate the exact degree of this resistance. By adjusting the said brake so that the flanges j, which are vertical, whereas the body of the brake is horizontal, shall be more or less presented to the fl-ow' of liquid, this resistance is varied at will. This brake consists of a flat disk turning in the inner case and supported there- IOO by, and having openings J cut in from the periphery thereof at intervals, leaving horizontal plates between them. From oneedge of each plate one of the said vertical flanges j extends downward.

To allow the axial adjustment of said brake as stated, the periphery thereof may be provided with eogsj, as shown in Fig. 5, which mesh with a worm, S, on a spindle, S, that extends outward through the casings D and A. The same object may be eifected, as shown in Figs. 7 and 8, by a bolt passing through a slot in said brake, or the brake may be made of resilient metal and rather greater in diameter than the interior of the inner case, D, and slotted at j so that it may be squeezed within the same. It will then fit tightly, but may be turned by hand to the desired position of adjustment. An opening, closed by a screwplug, N, in the side of the outer casing under the outlet A facilitates the cleaning of the interior of said casing.

Brakes have been long known and used in meters of this sort, but an adjustable brake interposed between the inlet and outlet is found to operate more satisfactorily than any other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

3. The combination of a removable inner meter-casing having an external annular beveled shoulder with an outer casing and an internal elastic packing-ring interposed between the two casings, which fits on said shoulder and is compressed thereby to form a watertight joint, substantially as set forth.

4. The stationary-adjustable brake J, hav iug openings J and flanges j, and arranged between the inlet and the outlet, with the fan and casings of a meter, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

JOSEPH JOHN TYLOR.
